Novel inward-fed rotary filter screen type grille decontamination machine

Abstract

The invention relates to a novel inward-fed rotary filter screen type grille decontamination machine, comprising a full-closed box type machine body, a reducer, a spindle, chain wheels, a network chain plate and a spiral conveying presser. The reducer is fixedly mounted on one side of the upper end of the machine body, the power input end of the spindle runs through the lateral side of the machine body to be connected with the output end of the reducer, the chain wheels are mounted at two ends of the spindle, the network chain plate connectively sleeves the chain wheels and surrounds the spiral conveying presser positioned under the chain wheels, flushing devices positioned below the spiral conveying presser are arranged in the network chain plate, water baffles are arranged on the left and right sides of the lower ends of the network chain plate, and a sweeping device is arranged at an included angle formed by the lower end of each chain wheel and the network chain plate. The novel inward-fed rotary filter screen type grille decontamination machine has the advantages of simple structure, good convenience in operation and maintenance, high contamination prevention efficiency, small occupied space with the help of the added spiral conveying presser, low energy consumption, high dewatering efficiency, good convenience in scum conveying and high capability of avoiding scum wastewater causing environmental contaminations.

Description

technical field [0001] The invention relates to a grid decontamination machine, in particular to a new type internal rotary filter grid decontamination machine, which belongs to the technical field of sewage treatment equipment. Background technique [0002] During the cleaning process, the traditional tooth rake cleaning machine can only clean up the relatively large volume of sludge, and the small volume of sludge cannot be completely cleaned up, resulting in the small volume of sludge entering the sewage treatment process. It will bring pressure to the subsequent sewage treatment, and the larger sludge is more likely to remain on the tooth rake cleaning machine. When there is a lot of sludge residue, it will affect the normal operation of the equipment; The body, transmission mechanism, net chain plate, water retaining device, etc. are generally installed in the water intake of each power plant or in the channel of municipal engineering.

[0002] During the cleaning process, the traditional tooth rake cleaning machine can only clean up the relatively large volume of sludge, and the small volume of sludge cannot be completely cleaned up, resulting in the small volume of sludge entering the sewage treatment process. It will bring pressure to the subsequent sewage treatment, and the larger sludge is more likely to remain on the tooth rake cleaning machine. When there is a lot of sludge residue, it will affect the normal operation of the equipment; The body, transmission mechanism, net chain plate, water retaining device, etc. are generally installed in the water intake of each power plant or in the channel of municipal engineering. The decontamination machine is used to intercept small debris and floating However, the small debris remaining on the filter is not easy to clean, which reduces the antifouling efficiency and easily causes secondary pollution to the clean water area; the slag of the traditional internal rotary filter is discharged into the slag collection tank, and then relies on the nozzle The flushing water flows automatically into the drainage conveying tank, and finally is conveyed and squeezed into the garbage trolley through the high drainage press. The whole process requires more equipment and occupies a large area, resulting in large energy consumption.
